Find the probability.

You flip a coin and then roll a fair

six-sided die. The coin lands heads-up

and the die shows a three.

1/2 or 50%

Step-by-step explanation:

In a coin there are only two sample spaces and two outcomes. Of those two, only one will show up, either heads or tails.

In a dice, there are 6 sample spaces and 6 different outcomes numbered 1-6. Of those 6, only one number will be rolled, either 1,2,3,4,5,6.

Since the coin showed heads up, and there are 2 possible outcomes, it showed one of those 2, which is heads. That is 1/2 or 50%.

Since the die showed one number (3) out of the 6 possible outcomes, then we know that it is 1/6 or 16.666 ... %.
